To all whom t covwera.'V 1 f Be it known that I, JOHN C. FIDDYMENT,

a citizen of the United lStates,-ia11"d residentr of Mountl Gilead, inthecounty of yMorrow 6 and `State of Ohio, have nventedfcertain new anduseful "Improvements Presses, of Which the following is'a'spec1'ieat1on-- This invention relates to a continuous' press for usein -pressing oil seeds, nuts, soy 1 beans, copra, 'and in general anysubstance fromfwhieh fat, oils 0r other fluid may bey and'aroundasp-rocket'wheel: 19 on 'a shaft expressed. y. .Y

An object of the invention is to 'provide such a press which Willhaveavconstant.y rotation in one direction, and Willi'handle various materialseheiently' and rapidly. 1 f r Another object is vtov-'provide means fordraining out the liquid rapidlyasthe material is pressed and' finallydisposinglofy the material remaining' after lthey extractionI of thefluid in such 'a manner thatthe press may operate continuously and atthe' same time exert sufficient pressureto express the fluid thoroughly;

At one end the casing 36'has its lower side. cut away andcommunicatesvwith the upper'cut away side of the casing 53 which is notquite cylindrical in shape. The cas-l ing 36 and casing-53 are shown asbeing made integral but of `course thisfis not essential. .Within thecasing 53 is` a two part bearing member 54 in which is mount-r ed ashaft 55 asfshown in'Figure 4. Since the casing lune shaped member 56 isplaced in the bottom thereof, having curved to correspond with thebearing 54.`

This isl adjustably held in position by a screw 57 as shown in Figure 4,andi-un.

shaped member 56 may be removed endwise. This will permit thel bearing54 and shaft 55'to. drop down to a position from which itxmay also beremoved through the o en endof the casing 53. This bearing 54 a soprevents thrustv-.tendingto force sides of B and .C against walls of'channels E and F.

YAt one side there is `an Yopening through the casings 36 and 53 attheir juncture with which communicates the Yfeedpassage 34.

The material is. fed from the hopper by Ythe screw 33 through thepassage 34 into lthe casings 36 and 5K3- at theirv juncture, and isthere received by feed mechanism which transmits it to the screw 42.

This feed mechanism 1s yo 53 is not-entirely cylindrical, a

its upperv surface` f olutions ofthe shaft' 1 6.A

acter and is illustratedin Figs. 4 to 7 and 9. The shaft 55 is providedwith three ring like members A, B and C. The member A has six teeth a asshown, while the members vB and C have -threecut outs b and 0respectively. Each of the three cut outs is yapproximately oneesixth ofthe circumference in extent, and the two-members B and C are located onthe shaft 55 in such relation that a cut out in one member comesopposite the solid portion of the other. The three members A, B and Care separated from each other lengthwise of the shaft 55 by portions ofthe bearing 5 4 as shown clearly in Figure 4.

The shaft 16 has` three portions D, E and and C respectively. Themember-Dirhas two cut outs d diametrically opposite and separated byriby portions d. Each cut out is U approximately one-sixth of thecircumference 1n extent. 4The portions E and F are channels formedbyz-ribs on the. shaft,

and each has a projection e and f respectively which is or may be aboutone-sixth ofthe circumference, the projections@ and f being arranged sovthat they always ex-` -A cooperate tohold the shaft 55 kagainstmovement except at two points in therevolution of the shaft 16. Whenevera cut 'outv vtlf-comes oppositea tooth a, either the pro-` jection e isin positionto cooperate with a cut out b in the member Bor theprojection f is in position to cooperate with ka cut out c' inthemember'C.l In either case'the shaft is given a one-sixth revolution.While the rib Z is in the position shown in Figure 5, where itvpractically contacts .with two teeth a, the member A is held againstmovement. Itis evidentthat the shaft 55 is driven in this manner step bystep lfrom the constantly rotating shaft 16 and is given one completerevolution bythree rev- In Figs. 5, 6 and 7, as the shaft 16 is revolvincounter clockwise.

The vmaterial vis fed by t e screw 33 intothe channel in the member E atthe point X, and the projection e ismoving away 'from the incomingmaterial whichfills up the channel behind the same until the projectione has made nearly a revolution, when the ymaterial passes through al cutout be# hind this projection or stop e into the next channel. In similarvmanner the material thus Vpassed vinto the second channel kis passedthrough another cut out inlfthe vchannel F. The channels E and Fareseparated by a-channel as sliown'in Figure [4 which well vas Fig. I3, i

comes opposite the wide bearingmember between the membelSB adf C,-v'vlldinally,the

material passes through a cutout from the channel F'to `the screwmembe1.42 fr i ,l

'Figure 9 is a development of the of the shaftlG having themembers' thedot and dash lineas shown from the oint of introduction'through the cutouts rom one channel to the succeeding one and a revolution, the memberB is stationary,

and the ri hery thereof engages-the bottom an si es of the channel' Eclosely enough to prevent any of the material which has been previouslylntroduced and is now on the pressure side of this stop e from comingback to the starting point. It is therefore forced into the adjacentchannel through the cut out in the walls of the first channel asdescribed. The same laction takes place in the channel F. These stopsformed by the rojecting portions of the members B and substantially fillthe channels and cannot be displaced in any manner. In Figures 6 and 7,for example the point marked H acts as a stopy for preventin thematerial from revolving with the sha t or passing this point. Theprojections e andA f can pass through b and c or b and c,-but

the material cannot follow, and while f is passin through c the channelis blocked by B, sot at if any material should get through while f ispassing it cannot get out into the feed. The material is thereforecaused to travel along under pressure to a point where it is taken up bythe screw.

It may be noted that this feed mechanis may be used Ywith other types ofexpressing apparatus, and is in no way limited to the specific form hereshown, although it coopcrates therewith.

The bolts 59, in Figure 1, may be used asA i jack screws to take thecasingoti' of .the

shaft if the machine stalls. these screw bolts is fixed and the other isscrew threaded and passes through thelugs as shown` v f f Means may beprovided if desired for varyin the Yrate of feed ofthe screw 33 since iecompression is affected by the amount of material fed into the firstchannel. It is obvious that vdetail changes ymay be made. in the preciseform and arrangement of various elements without departing from thespirit of the invention and it is to be understood that theinvention islimited by the scope of the appended claims.
